Application filed April 3, 1914. Serial No. 829,225.

To all whom it may concern: 7

Be it known that I, RAYMOND J. MILLER,

. of Rochester, in the county of Monroe and ings, forming a part of this specification,

and to the reference-numerals marked thereon.

My invention relates to beds for machinery of various types such as lathes and the like, and it has for its object to afford a machine bed that can be quickly set up on its foundation and provides a firm and stable base for the mechanism.

A further object of my invention consists in affording a supporting means that can be readily placed upon an uneven floor or foundation in such a manner as to eliminate he necessity of any difiicult adjustment in balancing the parts, while at the same time providing a rigid support for all parts of the machine, so as to obviate any twisting or torsional tendencies that would be caused by a foundation that is not entirely level.

To these and other ends the invention'resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end ofthe specification.

In the drawingsz'Figure l is a side elevation of a machine, showing one application of the invention; Fig. 2 is an end elevation, showing the supporting members at one end; Fig. 3 is an end elevation, showing the supporting member at the opposite end, and Fig. 4t is a bottom plan view.

Similar reference numerals throughout the several figures indicate the same parts.

In the present embodiment of my invenillustration of which is shown in the accompanying drawings, A designates a suitable bed upon which a lathe or other mechanism is arranged as usual in this class of machinery. In setting up heavy v machines of this character, difliculty is frequently experienced owing to the unevenness of the foundation surface, and this is generally overcome by inserting wedges or blocks under the supports until they are all in proper engagement with the foundation.

The objection to this is that in many instances, some portion of the machine is not 111 proper engagement with its foundation owing to the corresponding supporting memher being in spaced relation above it, and this often causes the machine, or the main frame work thereof, to become more or less warped or twisted. To overcome this, I provide a plurality of fixed supporting members to engage three points on the surface of the foundation, and in connection therewith one or more adjustable supporting members which cooperate with the uneven portions of the foundation and can be adjusted into intimate engagement therewith, causing the frame of the machine to be rigidly maintained in a correct and properly balanced position, rendering it free from any rocking tendency to which it would otherwise be subjected.

The frame is provided at one end with one or more fixed supporting members constituted in the present instance by the legs B and B, while at the opposite end there is embodied a single fixed supporting mem her or leg C. This arrangement permits of a fixed three-point support for the bed, and a machine can be properly positioned on any sort of foundation, whether of regular or irregular surface, by finding these three preliminary points of support. One end of the table being supported at only a single point, it is necessary to provide means for properly supporting the other portions of the same end so as to prevent any rocking, which would result from the use of the machine under certain conditions. To this end, I

employ one or more adjustable supporting members and in the present embodiment. there is provided a pair of vertically adjustable feet arranged on opposite sides of the fixed supporting member, the latter being substantially in line with the longitudinal axis of the machine. In the construction shown, the fixed leg G is formed on an end member D wh'ch carries extensions E disposed on opposite sides of the leg C and preferably terminating in a horizontal plane somewhat above the base of the leg C. The extensions E carry the adjustable supporting members or feet F which are provided with threaded posts F adjustable in threaded openings in the extensions E and held in place by the lock nuts F In the operation of the device, the bed is first positioned on its foundation upon its three fixed points of support, and the feet F are then adjusted until they are in engagement with the support as shown in Fig. .The lock nuts F may then be tightened to hold the supporting members in proper relation to the floor or foundation, thus affording a solid and rigid support for every part of the machine, irrespective of the contour of the surface of the foundation.

The structure which I have described affords an extremely simple andefficient means for leveling a lathe bed or the like,-permitting the machine to be operated indefinitely Without in any Way straining the supporting parts or legs, or affecting the proper cooperation of the mechanism.

I claim as my invention:

1. A bed for lathes or the like including plurality of fixed supporting members at one end, a pair of adjustable supporting members at the opposite end, and a fixed supporting member positioned between said adjustable members and provided With a flat bottom arranged to rest upon a foundation adapted to support said adjustable supporting members.

2. A bed for lathes or the like including a plurality of fixed supporting members at Copies of this patent may be obtained for five cents each,

one end, a fixed supporting member at the opposite end arranged substantially in line With the'lo-ngitudinal axis of the machine, and adjustable supporting members positioned on opposite sides of the last mentioned fixed supporting member and arranged to engage the foundation adapted to support said last mentioned fixed member. 3. A lathe bed or the like including a plurality of fixed supporting members at one end, a fixed supporting member at the opposite end arranged substantially in line with the longitudinal axis of the machine and terminating in a plane with the bottom of the aforesaid supporting members, extension members site sides of the last mentioned fixed member and terminating in a plane above the bottom of said last mentioned fixed member and adjustable supporting members mounted on said extension members, and arranged i to rest upon the foundation adapted to support the first mentioned supporting members.
